* limit the number of points in SkDashPathEffect::asPointsGravatar lsalzman2016-07-21
| | | | | | | | | | | | | | | | | | | If the length of a line path is sufficiently long relative to the dash interval, it is possible to cause SkDashPathEffect::asPoints to produce so many points that it overflows the amount that can fit in an int type, or otherwise produce non-finite values, i.e. path from (0,0) to (0,9e15) with a dash interval of 1. This fixes that by capping the amount of points to a sane limit - in this case, 1mil, since that limit is also used in utils/SkDashPath.cpp and has precedent.

* allow one zero length dashGravatar caryclark2016-03-18
| | | | | | | | | | | | | | | | | | If the constructed stroke that represents a dash has a single dash of length zero, and the end cap is square or round, draw the cap. The old code initialized the initial dash length to zero, making it ambiguous whether the first length is zero or not.

* Move Dashing filterPath to a dashing utils fileGravatar egdaniel2014-06-11
| | | | | | | | | | | | | | | | From inside GrContext, we have a need to create an SkPath an original path and some dashing info. We do not have access to the original path effect so we need a way to make the FilterPath function accessible outside of the effect. So I moved the core filterPath code (and all need helper functions) out of SkDashPathEffect and created a SkDashPath in utils to store these helper functions.
